Abstract
The influence of carbon fibre on the curing kinetics of the prepolymer base d on bisphenol A cyanurate and epoxy resin has been studied using infra-red spectroscopy. It was found that curing process of prepolymer is very compl icated. It is shown that in curing the prepolymer a number of the sequentia l transformations of ones cycle structure into others occurs. An introducti on of the carbon fiber (CF) of two types, original CF and modified CF (MCF) containing phosphate groups, affect strongly the prepolymer curing. Both C F and MCF accelerate the conversion rate of epoxy groups. In the case of cy anate groups, the former does not practically affect their conversion where as the latter decelerates strongly this process. In the paper the influence mechanism of CF is considered.
